The full screen mode is especially nice on iPad. Tap with three fingers and Chrome will expand to take up the whole screen. Chromizer also adds a pull to refresh option for any page you're on. More interesting is the new tab switching for the iPad version. Chromizer essentially brings the sliding finger switching of the iPhone version Chrome to the iPad, and it works great. Chromizer isn't a huge tweak, but it works well and adds a few really nice features to Chrome. You can download it free from the ModMyi repository in Cydia.
